Background

Primary immunodeficiency diseases are diseases in which the immune system has a defect that render patients more susceptible to infections. If left untreated, these infections may be fatal.

Patients with common variable immunodeficiency (CVID), which is a common type of primary immunodeficiency (PID), are prone to upper and lower respiratory tract infections.

Primary immunodeficiency is not rare. The U.S. National Institutes of Health report that as much as 1-2 percent of the U.S. population is affected. That's 3-6 million Americans, and about 98-99 percent do not even know that they have it.The condition is more prevalent than childhood Leukemia and Lymphoma combined and four times the incidence of Cystic Fibrosis (Jeffrey Modell Foundation).
